WATER=MOTOR.

SPECIFICATION forming part of Letters Patent No. 393,316, dated November20, 1888.

Application filed March 27, 1888. Serial No. 268,668. (No model.)

To all whom it may concern.-

Be it known that I, HENRY E. TRUMBLE, a citizen of the United States,residing at Kalamazoo, county of Kalamazoo, State of Michigan, haveinvented a new and usefulWater- Motor, of which the following is aspecification.

This invention is especially designed for the employment of water as themotive power to operate it; but I do not limit it to water, as steam andair, &c., may be utilized to run it. Its general nature consists in asuitable frame, case, or support, to which a piston-head composed of twoplates hinged together is pivotally attached at the end of one of theplates, the free end of the other plate being left free to vibrate inthe water, steam, or air, 850., as clearly and more particularlydescribed below. The piston-head so called,may properly be termed ajointed lever, but as it is a piston-head in its functions, forconvenience I employ this term.

In the drawings forming a part of this specilication, Figure l is a Viewof Fig. 2, looking from apoint at the right, with a part removed; andFig. 2 is a view of Fig. 1, looking from a point at the left.

Referring to the lettered parts of the draw ings, A is a flume having amouth at one end to admit the waterupper end in Fig. 1-and aneductionopening at the other end. This flume would ordinarily receivewater from a race or water-supply pipe, or it can be sunk in a flowingstream. The latter is my design in most instances, and to this end Fig.1 may be considered to represent an open frame or support, for when themotor is located at the bottom of a flowing stream with a strong currentit does not matter that the frame should have closed sides to preventthe escape of water except through the eduction end, because the wateris plenty and does not need to be confined except by the banks of thestream; but when steam or air is employed, or the supply of water comesfrom a mill-race or pipe, as above stated, then the support to thepistonhead should be a flume with its sides inclosed, as in Fig. 2. Tomake it more clear, the end of the piston-head at a, Fig. 1, could bepivoted to a block or to a stake driven in the bed of a stream in lieuof pivoting it to the wall of the flume, as here shown, and the stops 6a could consist of stakes, or anything to limit the vibration of thefree end of the pistonhead. The two plates B B are hinged together at c,Fig. 1. The pivot a, in this instance, is ashaft to which the crank D isattached. During the operation this crank vibrates, and by means ofsuitable parts (not here shown, but which will be readily understood)rotary motion is imparted to machinery.

The operation of the piston is as follows: The water, flowing in thedirection of the arrows, presses against the oblique side of the upperplate B, which causes both plates to assume the position shown by dottedlines 1 2, at which time the water presses against both plates, carryingthem on to the position 8 4. The upper plate has here met the stop 0 andinclines in the direction opposite to that at the point of starting. Thewater then throws the upper plate B over to the position shown by dottedplate 5, and the same action of the piston-head above described takesplace, but in the opposite direction. Thus the operation of the jointedpiston-head automatically continues, the plate having the free endvibrating on its pivotal attachment with the other plate, and the latterplate vibrating on its pivotal attachment with the support or frame. Thestops 6 e prevent the plates from folding together upon themselves, andthe stops 0 0 cause the plate having the free end to assume the properangle, as before stated, so that the water will wedge in back of it andtilt it over to the position shown by dotted plate 5. The stops 0consist of screws adjustable in the sides of the frame A. By screwingthem farther in the pistonheads will vibrate fasterthat is, the strokeback and forth from one side to the other will be oftener and shorter.

At S, Fig. 1, I have shown a broken pistonrod pivoted to the end of thelower plate 13 near the hinge c. It may be near to or at the hinge. Thispiston shows that the jointed plates perform the functions of apiston-head, and said piston may be employed as an equivalent to thecrank-shaft before described, and accomplish the same results oftransmitting rotary motion to machinery.

Having thus described my invention,what I claim is- A motorcomprisingasuitable frame or support, a pistonhcad consisting of twojointedly-connected plates, the end of one plate pivoted to the support,a crank-shaft or its specified equivalent, and suitable stops tolimitand 5 control the vibration of the piston, substantially as setforth.

In tcstimonyof the foregoing Ihavehercunto HENRY E. TRUMBLE.
